GLENDALE, Ariz. (AP) The Los Angeles Dodgers are confident the free-agent acquisition of Tom Koehler will help fill a bullpen void left by Brandon Morrow's jump to the Chicago Cubs.

For Koehler, it's a move that represents a transition that began last season, first in Miami and then in Toronto. That's when the starter began to re-invent himself as a reliever. More important, perhaps, that's also when the right-hander showed that maybe he had the ability to complete the move. Call it a career change-up.

Koehler, a starter with mixed results from 2014 through 2016 with the Marlins, is as confident as the Dodgers are about his chances at succeeding in the bullpen. For him and the club, it's about fit and philosophy.
